我正在尝试创建一个mysql查询循环，以在xlsxwriter php excel exporter中实现它，但我很难让它工作，它生成excel表，但它说它已损坏，无法工作。
这是原始文件源代码：

<?php
include_once("xlsxwriter.class.php");
ini_set('display_errors', 0);
ini_set('log_errors', 1);
error_reporting(E_ALL & ~E_NOTICE);

$filename = "example.xlsx";
header('Content-disposition: attachment; filename="'.XLSXWriter::sanitize_filename($filename).'"');
header("Content-Type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet");
header('Content-Transfer-Encoding: binary');
header('Cache-Control: must-revalidate');
header('Pragma: public');

$rows = array(
    array('test','1','-50.5','2010-01-01 23:00:00','2012-12-31 23:00:00'),
    array('2003','=B1', '23.5','2010-01-01 00:00:00','2012-12-31 00:00:00'),
);

$writer = new XLSXWriter();
$writer->setAuthor('Some Author'); 
foreach($rows as $row)
    $writer->writeSheetRow('Sheet1', $row);
$writer->writeToStdOut();
//$writer->writeToFile('example.xlsx');
//echo $writer->writeToString();
exit(0);

这是我创建的代码，您会注意到在“writesheetrow”行中，我创建了一些伪数据，只是为了检查它是否工作，而不是

<?php
include "session.php";
include_once("files/excel/xlsxwriter.class.php");
ini_set('display_errors', 0);
ini_set('log_errors', 1);
error_reporting(E_ALL & ~E_NOTICE);

$filename = "example.xlsx";
header('Content-disposition: attachment; filename="'.XLSXWriter::sanitize_filename($filename).'"');
header("Content-Type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet");
header('Content-Transfer-Encoding: binary');
header('Cache-Control: must-revalidate');
header('Pragma: public');

$writer = new XLSXWriter();

//define column headers
$headers = array('Product Id' => 'integer', 'Price' => 'price', 'Sale Price' => 'price', 'Sales Count' => 'integer', 'Sale Date' => 'string');
//write headers
$writer->writeSheetHeader('Sheet1', $headers);

            $sql = "SELECT * FROM customeracct WHERE tourid=1005 AND status=1";
            $result = $db->query($sql);
            if ($result->num_rows > 0) { while($customeracct = $result->fetch_assoc()) { 

                $contactid = $customeracct["contactid"];
                $contactsql = "SELECT * FROM contacts WHERE id=$contactid";
                $contactresult = $db->query($contactsql);
                $contactcustomer = $contactresult->fetch_assoc();

                //write rows to sheet1
                $writer->writeSheetRow('Sheet1',array('test','1','-50.5','2010-01-01 23:00:00','2012-12-31 23:00:00'));
            }}

$writer->setAuthor('Good Shepherd Travels'); 
exit(0);

你能帮我检查一下它是否正确，或者有没有更好的方法吗？我尝试在数组中创建循环，但是在数组中使用php条件代码是行不通的。
谢谢您。
